emacs 24.4.1 image support - can't find libpng16.dll binary

Question

I am using Windows 8 64bit trying to get image support for emacs. Here is the result of Ch Ca GNU Emacs 24.4.1 (i686-pc-mingw32) of 2014-10-24 on LEG570

here is dynamic-library-alist:

((xpm "libxpm.dll" "xpm4.dll" "libXpm-nox4.dll") (png "libpng16.dll" "libpng16-16.dll") (tiff "libtiff-5.dll" "libtiff3.dll" "libtiff.dll") (jpeg "libjpeg-9.dll") (gif "libgif-7.dll") (svg "librsvg-2-2.dll") (gdk-pixbuf "libgdk_pixbuf-2.0-0.dll") (glib "libglib-2.0-0.dll") (gobject "libgobject-2.0-0.dll") (gnutls "libgnutls-28.dll" "libgnutls-26.dll") (libxml2 "libxml2-2.dll" "libxml2.dll") (zlib "zlib1.dll" "libz-1.dll"))

Here is the contents of emacs24/bin:

My problem - I can't seem to find a BINARY for libpng16.dll or libpng16-16.dll. Lots of source code out there but no binaries. I found libpng15-15.dll in both 32 and 64 bit versions at /www.gtk.org/download/win32.php - not that I know which of the two would work. I can NOT find libpng15.dll either - I am using a 64 bit windows8 computer but I THINK the emacs precompiled version that I am using is 32 bit.... Can anyone help?

从http://sourceforge.net/projects/ezwinports/files/下载libpng-1.6.12-w32-bin.zip，然后将libpng16.dll和zlib1.dll复制到emacs24 / bin（需要zlib1.dll）
